As Hurricane Matthew runs along the Florida and Georgia coasts — and having already caused hundreds of deaths in Haiti — perhaps you've seen images of what appear to be sharks swimming in flooded streets.
These images — which are hoaxes — are nothing new.
They frequently pop up during hurricanes, and are spread far and wide through social media, even years after being proven false.
Most of these images are created by editing two photos together. For example, here's one of the most popular hoax pics, as compared to a photo someone took while shark diving in South Africa in 2006, which can be found on Flickr.
And this picture, which is frequently claimed to have been taken during Hurricane Sandy (and basically every hurricane since) actually comes from a 2005 issue of Africa Geographic.
Initiated by trolls and attention-seekers, propagated by people's legitimate fears — and in spite of repeated debunking — these images continue to spread.
So, next time you see a shark roaming the streets during a hurricane, be vigilant.
It's probably/definitely fake.
